My SIM card seems abnormal. I want to replace it.

Dear Public Mobile service officer,

My cell phone signal is sometimes not available at home, at school or on the road. This situation adds a lot of trouble in my daily life. Due to the loss of the signal, I missed a job confirmed phone and text message yesterday. At the same time and place, people around me who use the same public mobile phone service, their mobile phone service is normal. I wish you can help me to replace my SIM card for free to fix my problem.

Not sure how you determined that the issue is your sim. Why don't ask your friend that has connectivity where you don't if you can use their card in your phone. If you still lose connection the the problem is your phone.

The model of my phone is XiaoMi 8. It's normal previously. I used the SIM card on my friends and lost the signal also. I reset my cell phone several times. It works normally when I reset my cell phone. But it will abnormal sometime later. This status is also on my friends' iPhone Xs when they were used my SIM card. They work normally when they use their public mobile SIM cards.
